Hello! Found a strange behavior of Windows volume level regulators. If a driver returns a volume level range that crosses the zero (-n..+n dB), Windows volume control applets (XP and Win7) make a very uneven scale for the sliders. For example, if the range returned is -90..+90 dB, the "0 dB" position is about 5% from the bottom (almost a lower position). If the range is -90..+60 dB, the zero position is a little higher (about 7%). Only with a very narrow positive range (-90..+12 dB), the zero position is near to the center. It looks like a "logarithm of a logarithm", i.e. a slider scale is double-logarithmic, while it should be linear for the dB levels. Why volume control application do such strange scaling? Maybe there is a way to make a linear slider scale?
